'To all whom t may concern:

Be it known that I, Gnoncn W. PRIEST, of Newton, county of Middlesex, State of Massachusetts, have invented an Improvement in Apparatus for Lining Pipes, of

which the following is a specification.,

This invention relates to improvements in ,apparatus for lining pipes with cement or similar material, such for instance as disclosed in United States Patents #750,660, and #790,372, itrbeing especially adapted for lining pipes of large diameter. y

The invention has for its object to provide means for compact-ing t-he cement in the space adapted to receive it by jarring it, which consists in jolting, shaking or otherwise vibrating the pipe or some part connected therewith; also t'o provide means for supporting the pipe to'be lined, and a core,

or otherwise vibrating the pipe-supporting means and parts connected therewith, to jar the cement and cause it to become firmlyv compacted in the space between the pipe and core; also to provide a cement-container which is connected with the pipe-supporting means, so that the vibrations may be irnparted thereto, whereby t-he cementis jarred andcaused to enter the space adapted to-receve it` andy to become firmly compacted therein; also to provide means for supporting and lining thepipe and means for eX- hausting the air from the space to be filled with cement, and means for vibrating the lpipe to jar the cement and cause it to become compacted in said space; also to pro's vide said vibrating parts with means whereby pressure maybe applied to the material which is contained in the space betweenthe pipe and core, such means being arranged to be thrown into operationwhenever desired, although ordinarily employed only when the space has been completely filled, yet said pressure applying means may be omitted; also, to provide a hollow-core which is in open-communication with a vacuum-box and which is perforated to permit the passage of airf through it, but to prevent the passage of cement therethrough; also, to provide a flask for holding the pipe, which is substantially constructed, so that the pipe which is employed may be composed of thin sheet metal.

Figure 1 is a side elevation of an apparaand means for repeatedly jolting, shaking being arranged' within an inclosing-case preparatory to being lined. Fig. 3 is a front View of .theinclosing-case for the pipe, it being shown in'closed position. Fig. ltis a front View of the 'mclosing-case when opened. Fig. 5 is an enlarged plan view of the inclosing-case and `pipeesupporting means, and the core and core-supporting means. Fig. 6 is an enlarged plan view of theto-pfplate of the vacuumlbox, which also serves as the lower end-support for the vpipe and core. Figa 7 is a detail showing the guides for the movable vacuum-box. Figs. 8 and 9 are sectional details showing the parts provided with means for withdrawing the core.

a represents a supporting-plate for the pipe, which is arranged. to support a core which vis containedwithin the Apipe and also a flask, providing a flask is employed, which in many instances is not necessary. Said plate is adapted to be arranged on top of a vacuum-box b, of any suitable shape, size and construction, which lis connected by a pipe b, with any suitable means for exhausting the air therefrom. In this instance, as the machine is particularly desired for lining or making composite pipe of large diameter, said supporting-plate a will be made of large diameter and consequently is quite heavy. It is removably placed on top of the vacuum-box, and by reason of its weight and of th'e weight of the parts placed upon it, it need not necessarily tbe connected to said box.

The pipe shown vlin Fig. 2 is one of the many forms the present machine is adapted to line with cement, and comprises a plurality of tubular met-al sections of any usual or suitable construction concentrically arranged one within another, with spaces between them, and cement contained in the spaces between. the sections and alsov arranged on the interior of the inner pipe section. The two tubular metal sections c, c are here shown extended the full 'length of thefpipe to be made, and in the socketed v is employed. The supporting-plate a has a seat, formed asa shoulder a, for each pipesection which is employed in the manu/fac-v ture ofthe pipe, and, as here. shown, it hasV4 three concentrioally arranged seats, and the!f several pipe-.sections are arranged indipright position on said supporting-plate with their lower ends in engagement with said seats. As here shown, in/Fig. 2 provision is made for a socket-pipe, and the socketed portion of the pipe is arranged at the lbwer .end and the supporting-plate a is made large enoughv to receive it. The supporting-plate a is also adapted to support a core ,which is contained in the pipe and which is subselquently withdrawn after the pipe has been vlined and thelining has become set. To

thus adapt the Asupporting-plate to receive the core it is herein formed with a central raised portion a2, having a recess in its .upper side of suitable size and shape to re- .ceive the lower end of the core d. The core herein shown is made hollow, because the water to be. drawn through them into the pipe. which is being lined is of large diameter, and it is' provided with perforations 4along its uprightwalls as shown at d. Said perforations are herein shown as arranged in groups located at short distances apart but they-may be otherwise arranged. They are made very small to permit the -air and core, and yet prevent the cement from passing through them into the core. The several groups are arranged throughout the length of the core, preferably at distances apart toward the upper end thereof. The supporting-plate a is provided with numerous per- -forations as whichr connect the spaces between the several pipe-sections, and between the inner pipe-section andcore and also the interiorv of the core, with the interior of the vacuum-box b. All of the perforations are made very small. On top of the supportingplate, over the perforations, gauze rings a4 or equivalent means lare placed to prevent the cement passing through theperforations into the interior of the vacuum-box.

As the particular form of pipe hereinshown for the purpose of illustrating this invention comprises several thin tubular metallic sections it'is necessary to support theml to prevent them from bursting while the cement is being compacted in the spaces bes 'semicircular portions connected together and each embraces a part of the ask so that when the two parts of the flask are closed together the two semicireular portions clamps ma be connected to securely hold `fthe parts o the iiask in closed position. The supporting-plate a is also adapted to receive uponit said ask e, e.

l In addition to the aforesaid clam other clamps are provided for securely olding of the the parts ofl said iiask in lclosed position, as

many being employed as necessary. All of the clamps are connected by brackets e4 to an upright bar e5 which is arranged in a vertical guideway formed in an uprightpillar e8. Said guideway provides for vertical movement .of said bar and of the flask connected therewith, and is employed for the purpose of enabling the pipe-supporting means to be jolt/ed or shaken for the purpose of causing the cement or other filling or lining material to enter the space or spaces between the pipe-sections and between -the linner pipefsection and core, and to become firmly compacted therein, as .will be described. 4

'As' a support `for the upper end of the flask and pipe-sections and hollow core, a rino f ,is mounted on theupper end of the liasr, having an inwardly extended flange which extends over the upper end of said flask; and the inner diameter of said ange 'is the same as the external diameter of the outer pipe-section, so as to engage the side of said outer pipe-section and support it against lateral movement. 'Said ring is rabbeted at its upper side to receive and support a ring f which extends over the upper end of the outer pipe-section, and said ring f has several inwardly extended fingers f2, whichy extend over the upper end of the inner pipe-section. Said fingers are shouldered at their under sides to provide seats against .which the upper end of said inner pipe-sectionbears. Said fingers are made narrow so that the space between the outer and inner pipe-sections is open for the most part to permit passage of the cement or other filling material. Said fingers are also beveled on their upper sides. The upper end of the hollow core d is closed, as at d2, and said closed end has an upwardly extended boss d3 which is externally screw-threaded. A plate f3 rests on top of the core having radially extended fingers f*,which are designed to extend over the nger's f2, and. it also has a beveled edge f5 terminating substantially flush with the side of the core. By the engagement of the lingers f4 with the fingers f2 said core is supported centrally in the inner pipe-section. Said lingers f4 are also made quite narrow so-that the space between the core and the inner pipe-section is open for the most part. A nut f is turned onthe screw-threaded boss on the core to hold the plate f3 in ixed position thereon. A tierod f7 extends down through the 'boss and core, the lowerlend of which engagesthe supporting-plate a, at the lower end of the core, as shown in Fig. 2. A cap f1 is placed on the plate f which incloses the nut`on they .upper end of the tie-rod.

g represents the cement-container, which consists essentially of a cylinder, open at the top and bottom, and having at its lower end an outwardly extended flange g', and the lower end of the cylinderl is formed with an annular grooveA which is adapted to receive a rib f formed on the upper side of the ring f. The cylinder is adapted to be detachably connected with the ring 7 by suitable clamps, and when thus secured 1n` or it may be a boss, which is engaged by a cani h secured to a rotatable shaft adapted to be driven by power, and said cam is so shaped as to raise the vacuum-box and-pipesupporting means and parts connected .therewith and then to permit said parts to .fall suddenly, by gravity, and as a resulta severe jolt is given to the aforesaid Vparts which results in the 'cement being irmly compacted in the spaces .provided for it.

Upright guides j are provided for the vacuum-box which permit of its free up and vdown movement and hold it against lateral movement.

The means thus described permits a jolting or sha-king movement of the pipe-sup-l porting means and parts connected therewith in an upward and do` nward direction, but my idvention in this particular is not limited to jolting or shaking the pipe-supporting means and parts` connected therewith in any particular direction; or to imparting vibrations to said means by a jolting or shaking operation, or to j olting, shaking or yotherwise vibratin all the parts, as the result which it is desired to accomplish is merely to impart to the pipe a vibrating movement so as to jar the cement and cause it to'become rmly compacted in the space adapted to receive it, hence my invention comprehends any means which may be employed for imparting vibrations to the pipe whereby this result may be accomplished.

At `any sta-ge. of the operation pressure may be applied to the cement contained in the cement'container, by means oi` a piston p which is arranged -above the cementcontainer and is adapted to be moved down into said container whenever desired. The lemployment of the piston or .any other means for` applying pressure to the cement contained in the cement-container is optional, although if employed it will be most effect-ive after this cement has been jolted down into the spaces adapted to receive it.

After the pipe has been formed or lined ,the flask and pipe-supporting means connected therewith are bodily lifted a short distance to disengage the vacuum-box, and they are then free to be moved along lonto a truck, and by said truck to be conveyed to a suitable appliance by which the core may be withdrawn. For the purpose of thus lifting the flask and parts connected therewith and also contained therein a cam m is arranged beneath the upright bar e5, which is l adapted to be operated by a suitable handpiece m or otherwise to lift said bar.

Referring to Figs.` 8 and 9, withdrawing means for the core are Shown, and in said figures a top-plate 7c is screwed onto-the boss on top of the core having a hook le which is adapted to be engaged by a suitable tackle for the purpose of-lift-ing the core, and said plate is made of a diameter correspondingto the` outside diameter of the pipe so as to eiitend over the same and its linings.

The composite pipe is herein shown as havinga lining of cement arranged in the inside of the inner pipe-section, but in case of a pipe-composed of a plurality of pipesections the cement contained in each space sefrves asalining for the section outside o it.
